[Postlabyrinthine approach of cerebellopontine angle surgery via endoscope]
1Department of Otolaryngology, The First People's Hospital of Huai'an, Huai'an 223300, China.
Objective:
To estimate the value of endoscope on postlabyrinthine approach of cerebellopontine angle surgery.
Method:
Transpostlabyrinthine endoscopic excision of glossopharyngeal nerve to treat 2 glossopharyngeal neuralgia patients. Observe the endoscopic eyespot and estimate the appliance and virtue of the surgery.
Result:
The two patients both have satisfied outcomes and remained free of disease after surgical treatment. We got a wide eyespot from trigeminal to vagus nerve. The internal acoustic porous is a fixed structure of the cerebellopontine angle and it is also a perfect landmark during the surgery.
Conclusion:
Endoscopic postlabyrinthine approach provides a shorter path to cerebellopontine angle and endoscope provides a unique way to explore the cerebellopontine angle and to identify the exact location of the pathological changes, including a multipoint of view. Complicated and skilled operation restricts the surgery.
